Adweek: What's the first information you consume in the morning? Christopher Meloni: Newspapers via my iPad. I read The New York Times and Wall Street Journal.

You're pretty prolific on Twitter, posting everything from political thoughts to beard selfies. How did you get started on there? It was about three years ago. I got involved through a woman named Tracey Pennywell who actually does this for a living. She managed my account, got me started, and then I took over. I treat it as a creative outlet. I've started thinking more that maybe I should just save that for my Facebook, but you can't do Facebook and Insta and Twitter. After a while, it's just like, holy Jesus. [Laughs] That becomes a full-time job unto itself. And there's something about 140 characters that I like. You have your say and make it a day.

How do you decide what to post? It seems very unfiltered, especially your photos. I just do what I do. I don't think about it too much. But I will say that there's a real hesitancy in me to put my family on there too often. That's why it's mostly selfies. I would prefer not to do any selfies, but it seems that that's what people appreciate and react to, so I'll feed that dog and I don't have a problem with it.

Who do you follow? I like Michael Ian Black, [Marc] Andreessen, Steve Martin. I like Dina Martina, who's a drag queen. Very kooky. I like Daniel Tosh, although I think he's got 20 million followers, and I really would appreciate it if he could give me, like, half of them. Just the ones he doesn't need anymore. And I love Johnny Knoxville. He's very funny.

What TV shows do you watch? First of all, Underground. Then The Knick and Fargo. I think that the last thing I binge-watched was The Knick.

What's on your reading list right now? I'm actually reading The Nine, which is about the Supreme Court justices in the Clinton/Bush era. The Rehnquist court and then the Roberts court. It's blowing my mind. The writer, Jeffrey Toobin, is really great. He's the guy who wrote the book The People vs. O.J. Simpson that the TV series is based on. Next up—I'm kind of going retro—is The Fatal Shore, which is the history of Australia. And I just finished The Human Stain by Philip Roth.

Print or e-book? I want to love the Kindle, but there's just something about a book. I love the texture of it. I guess you're just used to what you're used to.

You were great in the Wet Hot American Summer reboot on Netflix last year. Any plans for another season of that? I've heard that that is in the air. So we'll see. It was incredible. I was really so proud of David Wain and Michael Showalter, both what they wrote—the whole arc and everyone's individual storylines—plus being able to manage getting all the people back was a herculean effort.

Do you think we'll see you in any other comedy roles soon? I'm waiting to hear on a movie. Can't spill the beans! But it would be fun.
